Remember that you're never truly alone. There are people in the world who understand what you're going through and can relate. There are people who care about your well-being and want to make sure you're okay. There are so many wonderful people in this world, ones who will always be there for you.
Always try to empathize with others and make a genuine effort to understand their situation. You never know what another person may have going on in their life, what they might be dealing with. And you may not truly be able to understand until you get to know them better or experience their situation yourself. But, that's why rather than pass judgement on others, we should treat them with kindness and understanding instead. Show them tolerance and acceptance.
